GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(196, 790) = 77420
GCD(196, 790) = ( 196 x 790 ) / 77420
= 196 / 790
= 196
Step2:
LCM(2, 984) = 984
GCD(2, 984) = ( 2 x 984 ) / 984
= 2 / 984
= 2
Step3:
LCM(2, 985) = 1970
GCD(2, 985) = ( 2 x 985 ) / 1970
= 2 / 985
= 2
So, Greatest Common Divisor of 196, 790, 984, 985 is 1
